Abstract

The authors have studied the drying of cellulose particles under microwave irradiation. They consider the drying rate, temperature and complex permittivity of cellulose under various experimental conditions. A simple model is proposed, based on a first order kinetics law, the rate constant of which depends linearly on the square of the applied electric field. They suggest that water is directly removed from the surface of cellulose by an electromagnetic field independently of the temperature.
